NVIDIA working to show Fermi at CES

Recent reports from unofficial sources contradict official statements from NVIDIA which say that the company’s upcoming Fermi/G300 GPU will be available by the end of the calendar year.

Unnamed board partners cited at DriverHeaven and [H]ard|OCP claim that NVIDIA is working to have “some” Fermi sample boards running at the January, 2010 Consumer Electronics Show in Las Vegas. The implication here is that NVIDIA may very well miss that window to demonstrate working silicon to the public.

Of greater concern is the overall state of the Fermi project. If the company is hoping, rather than guaranteeing, to show the first public demo of Fermi in the second week of January, then the G300 may be further behind than anyone had imagined.

After the project slipped its original September/October launch, many believed that G300 would launch in the November/December time frame. That date was based on a July tape-out of the company’s A1 (first) G300 revision.

A tape-out is the finalization of a PCB/IC design; it is at this point that the schematics for the product are sent for manufacture. It typically takes about five months to translate the specs into a physical product. This is why a year-end G300 launch was expected from a July tape-out.

However, a tape-out is not always the last stage of circuit design. The design could fail viability checks at the foundry, or the production board may fail functionality checks in its shakedown cruise. Should either of these scenarios unfold, the circuit designer must commit itself to a new revision–a respin–which takes about 4-6 weeks from debugging to the very first test boards. Should that revision get a green light, you can add another 6-8 weeks for production boards.

EVGA GTX 275 CO-OP joins PPU and GPU on one PCB

Over the weekend EVGA announced the release of the EVGA GeForce GTX 275 CO-OP graphics card which places a GeForce GTX 275 and GTS 250 on the same board, with the latter serving as a dedicated PPU.

Technologically, the card is an interesting achievement in that “first and only of its type” sort of way.

But when it comes to value, the card takes a big tumble; there aren’t very many AAA titles with a notable NVIDIA PhysX implementation. We also have to consider the GTX 200’s march towards EOL and the introduction of the Radeon HD 5000 series, both which further erode this product’s value.

The GPU’s price is also of concern. With an MSRP of $349, the card is similarly priced to the GTX 285, an adapter which definitely has a leg up in the performance department (to say nothing of the 5850).

Maybe somebody really loves Arkham Asylum this much.

TSMC 40nm yield issues to hamper new GPU production

Digitimes is reporting that the Taiwan Semiconductor Manufacturing Corporation (TSMC) is once again experiencing yield issues on the 40nm process node.

TSMC said it has seen yield rates for its 40nm node drop to 40% due chamber matching issues. Main customers for TSMC’s 40nm processes are GPU vendors AMD, which recently launched its new 40nm-based Radeon 5870 series, and Nvidia, who is scheduled to launch its 40nm-based GT300 series of chips in December, according to previous reports. TSMC’s recent issues may impact the shipping schedules of the GPU vendors, market watchers commented.

In addition to shipping schedules, the standing MSRPs of 40nm GPUs may also be compromised. Indeed, rumors have already begun to churn that the Radeon HD 5850’s price will soon increase as demand continues to outstrip supply.

AMD releases DirectX 11 GPU demos

AMD has recently released two DirectX 11 technical demos that are designed to run on the firm’s lineup of Radeon HD 5000-series GPUs. The new demos highlight features made possible by the advent of DirectX 11.

Ladybug demo

The Ladybug demo shows how DirectX 11’s Direct Compute architecture, which standardizes and facilitates GPU processing, can be used to simulate lens-accurate depth of field. Depth of field is a cinematography technique used to draw the draw the viewer’s eye, or to enhance emotion, by unfocusing unimportant scene elements. The specific technique used in this demo is called “lens-accurate” because it perfectly imitates the dynamics of a traditional camera lens.

Notice that blur increases as a function of distance from the virtual lens.

If you decide to try either of the two demos, Ladybug is certainly the more impressive of the two. We’ve had some time to play with and observe the demo on a large display, and trust us when we say it looks outstanding.

CoolIT announces sealed liquid cooling units for new ATI cards

Today CoolIT systems announced the Omni sealed liquid cooler for the new line of ATI Evergreen GPUs, such as the Radeon HD 5850 and 5870. One of the primary features they are touting is a new universal liquid plate that is meant to work on future GPUs as well as current ones.

Similar to CoolIT’s other sealed units, such as their Domino ALC CPU cooler, the OMNI looks to be a quiet, maintenance free way to enter the world of liquid cooling. No word on pricing yet, but if it’s in line with their Domino, it won’t break the bank. They will be demoing the unit live at the AMD Technical Forum in Taipei tomorrow.

Time to get serious: 3D content creation and the ATI FirePro V8750

Hollywood is intense. Today, you can go see a film like District 9 or Transformers 2 and be awed by the computer generated visual effects–imagery that mimics the nuances of reality to an unbelievable degree–and not even realize the minute details going in to the production of a shot or, more importantly, the astounding hardware used to create those effects. Animation and VFX studios use impressive machines to bring these films to life. These artists are not relying on Radeon and GeForce GPUs to render their work. No, they pull in the big guns–the workstation boards–to do the heavy lifting.

The workstation GPU market is vastly different than the desktop GPU market, despite radically similar hardware configurations. ATI and NVIDIA both offer workstation solutions, named the FirePro and Quadro lines, respectively. The drivers set these units apart from their desktop gaming-centric cousins. These graphics cards are fine-tuned and optimized to work exceedingly well in 3D and graphics packages, such as Autodesk Maya, Softimage, and 3D Studio Max. They are built with the professional artist in mind, not the high-end gamer and, as a result, the target audience of a workstation board is radically different.

Studios today deal with intense graphics production pipelines. Any and all rendering time is valuable, and costs money. These artists don’t need machines that can render a low polygon scene with pixel shader effects at 60+ frames per second. What they need are machines with hardware that can supplement viewport performance in applications, calculate incredibly complex object physics, and render out an image with thousands of elements, anti-aliasing, shader effects, applied simulations, ray tracing, and whatever else the shot calls for, and it needs to do all of this really, really fast.

Radeon HD 5900 series in the pipeline

ati_logoATI has just recently published a new beta for their Stream SDK, a package designed to assist developers in creating GPGPU apps for ATI graphics adapters. The new package primarily adds OpenCL 1.0 support and, while all of that is well and good, it has also tipped the firm’s hand by revealing evidence of the Radeon HD 5900 series.

A quick peek at the new INF file for the SDK-compatible GPU driver lists the following entries:

“ATI Radeon HD 5900 Series” = ati2mtag_Evergreen, PCI\VEN_1002&DEV_689C
“EG CEDAR” = ati2mtag_Evergreen, PCI\VEN_1002&DEV_68E8
“EG CYPRESS” = ati2mtag_EvergreenGL, PCI\VEN_1002&DEV_6888
“EG JUNIPER” = ati2mtag_EvergreenGL, PCI\VEN_1002&DEV_68A8
“EG REDWOOD    ” = ati2mtag_Evergreen, PCI\VEN_1002&DEV_68DE

What the 5900 constitutes is anyone’s guess. If history is any indicator, it should be a juiced-up version of the 5870 with higher frequencies as a result of improved yields.

Rounding out the list, we see Cypress (Radeon HD 5870/5850), Juniper (Radeon HD 5770/5750), and Cedar and Redwood which have not yet shown in the market. Those cards are believed to be low-end adapters suitable for the OEM channel.

ATI Radeon HD 5770 launches

Last Thursday we caught a glimpse of the Radeon HD 5770, but a few 3DMark runs didn’t really answer any questions. Wonder no more, however, as today is the day when the Radeon 5770 hits the streets.

official_radeon_5750_5770_table

The first thing that can be noticed is that the 5770’s specifications do not stray far from that of the 4870’s. When translating the paper to testing, the spread still holds true: The 5770 and 4870 trade blows, with the 4870 pulling a touch ahead. The 5770 lags behind when memory bandwidth is at a premium, while it pulls ahead when fill rate is at a premium.

ATI Radeon HD 5750 launches

Earlier in the month we spied the Radeon HD 5750 at a DX11 event in China, but we were left to speculate over specs and speed. Guesstimating be damned, though, as the 5750 is now on the shelves of etailers everywhere. Let’s take a look at how it stacks up.

official_radeon_5750_5770_table

The first thing that can be noticed is that the 5750’s specifications fall short of the Radeon HD 4870. When translating the paper to testing, the spread still holds true: The 5750 frequently falls short of the 4870, sometimes by over 20 percent.

From the perspective of competition, the GeForce GTs 250 is the 5750’s main opponent. There are no solid victories here, though. The 5750 and the GTs 250 trade blows every time you change the title or the resolution.
